funcparams — Parameters for a function referenced through a function pointer in a synopsis


Mixed Content Model

funcparams ::=


Common attributes


In some programming languages (like C), it is possible for a function to have a pointer to another function as one of its parameters. In the syntax summary for such a function, the FuncParams element provides a wrapper for the function pointer.

For example, the following prototype describes the function sort, which takes two parameters. The first parameter, arr, is an array of integers. The second parameter is a pointer to a function, comp that returns an int. The comp function takes two parameters, both of type int *:

  <funcdef>void <function>sort</function></funcdef>
    <paramdef>int *<parameter>arr</parameter>[]</paramdef>
    <paramdef>int <parameter>(* comp)</parameter>
      <funcparams>int *, int *</funcparams></paramdef>

Processing expectations

Formatted inline. For a complete description of the processing expecations, see FuncSynopsis.

Future Changes

The InterfaceDefinition element will be discarded in DocBook V4.0. It will no longer be available in the content model of this element.


These elements contain funcparams: methodparam, paramdef.
